In the world of cloud computing, security is crucial. When you manage virtual machines (VMs), you naturally want only the right people to have access, without unnecessary risk. This is where Azure Bastion comes in, a game-changer for secure RDP and SSH access. In this blog, we’ll discuss what Az Bastion is, how it works, and why it’s more secure than traditional RDP. 🚀
What is Azure Bastion? 🤔
Az Bastion is a fully managed service from Microsoft Azure that lets you securely access your VMs directly from the Azure Porta¹l. The best part? You don’t need a public IP address, and you no longer need to open sensitive ports such as 3389 (for RDP) or 22 (for SSH). 🎉 How it works.
- You securely connect to your VM through a browser, without additional software or agents.
- The service runs entirely within your virtual network (VNet), which means your resources remain private.
Why choose AzureBastion? 💡
With Az Bastion, say goodbye to traditional, less secure ways of managing your VMs. Here are the benefits in a nutshell:
- 🔐 No public IP address required: Your VMs remain secure within your VNet and are not exposed to the Internet.
- 🌐 Direct access through the Azure Portal: Connect to your VM without additional tools or configurations.
- 🛡️ Protection against port scans: By keeping ports such as 3389 or 22 closed, you prevent unwanted access attempts.
- 🚫 Reduced risk of attacks: Hackers using traditional port scans are fishing behind the net. No public ports, no risk! 🐟❌
- ⚙️ No complex NSG configuration: No need to set up complicated network security groups.

Difference between Traditional RDP and Azure Bastion 🌍 vs. 🏰
When managing virtual machines (VMs), it is essential to choose a secure access option. Below, we explain the key differences between traditional Remote Desktop Protocol (RDP) and AzureBastion.
- Access Method:
- Traditional RDP: Requires external software, such as a Remote Desktop Client, to access.
- AzureBastion: Built directly into the Azure Portal, eliminating the need for additional tools.
- IP address:
- Traditional RDP: Needs a public IP address to connect to the VM.
- AzureBastion: No public IP address required; everything stays secure within your virtual network (VNet).
- Ports:
- Traditional RDP: Port 3389 must be open, posing risks such as unwanted access.
- AzureBastion: No open ports required, so your VMs are better protected.
- Security:
- Traditional RDP: Prone to attacks, such as port scans and brute force.
- AzureBastion: Strong network protection without exposure to the Internet.
Latest developments in AzureBastion 🚀
Microsoft continues to improve Az Bastion with new features such as:
- Native integration with Azure Active Directory (Azure AD): manage who has access based on roles. 👥
